The Zamorakian hasta is made by taking a Zamorakian spear to Otto Godblessed, along with a payment of 300,000 coins. It is the fastest hasta in the game, being 0.6 seconds (1 game tick) faster than every other hasta. Despite the examine text calling it a spear, the Zamorakian hasta does not deal full damage when fighting the Corporeal Beast.

It is a popular weapon against certain monsters, often used against dragons of all types and Vet'ion, as it has the highest stab bonus in the game and a reasonable crush bonus. It also has slight defensive bonuses and a prayer bonus, although it can only give shared or Defence XP. All of the stat bonuses remain the same as a Zamorakian spear, and it retains its special attack, making it superior in all circumstances (except when fighting Corporeal Beast) as it allows for an off-hand equipment such as a shield to be used. In order to make or wield it, you must have completed the bow firemaking (you do not have to do the chewed bones part), barehand fishing and smithing of Barbarian Training.

The Zamorakian hasta has a special attack, Shove, which it shares with the dragon and Zamorakian spear. It pushes an opponent back and stuns them for three seconds, consuming 25% of the player's special attack energy.

The effects of this special are non-stackable, meaning that players cannot use the hasta's special attack on a target who is already stunned. In addition to this, players are given a one tick (0.6 seconds) period of immunity after a stun wears off in which they cannot be stunned again.

In addition, it cannot be used against large monsters, such as giants, because they are too big to push back. If a player tries this, the special attack does not occur and no special attack energy is consumed. A message appears in the chat box, reading, "That creature is too large to knock back!" A general way to tell if the hasta can use the "Shove" special attack is to determine how much space the target monster takes up. If it takes up more than one space, it cannot be shoved. For example, a player can shove an ice warrior, which takes up one space, but not an ice giant, which takes up four.
